Genesis 24:13-14

13Look, I am standing by the spring of water, and the daughters of the men of the city are going out to draw water.

14Now let it be that the young woman to whom I say, ‘Please tip your jar so that I may drink,’ and she will say, ‘Drink—and I’ll also water your camels’—let her be the one You have appointed for your servant Isaac. So by this I’ll know that You have shown graciousness to my master.”
